In this paper, we propose a home-networking service using mobile phone and ZigBee module. Recently, ZigBee is widely used for various applications due to its characteristics. Especially, it is generally adopted for home network services. We propose a new home network service model using mobile phones. In the proposed architecture, the mobile phones are connected to conventional home network appliances using ZigBee dongle. Also, several servers are implemented for service management. We implement the whole components of the proposed architecture and show the validity of the proposed method. With the proposed service structure, it is expected to provide various ubiquitous services for the user.

This article introduces developing trends of an "Ubiquitous Interface" as an access method for use of various network resources, such as public wireless networks and un-licensed wireless networks in ubiquitous sensor network environments, without troublesome settings or operations by users. "Ubiquitous Interface" is include a relatively wide sense meaning not only physical interface of specified device or between processors, but anything method for access USN. These "Ubiquitous Interface" able to provide seamless services that adapt autonomously to the user's movements and changes in the state of wireless resources. Recently, strongly recommended candidates are RFID, NFC, Multi-mode mobile terminal, Wearable computer and OSGi for integrated digital home networking system as a future ubiquitous interface. These candidates are have to have flexibility and multiple physical communication channel for seamless service hand over and serve easy connection at huge USN to user. And, must have flexible software structure and multi-functional middleware. Consequently, for more enhance performance of an ubiquitous interface and developing, need more structured and integrated future plan.

Upon the changes of human life style due to the distribution of ultra-high speed internet services and the development of high-tech information equipment, the idea of necessity fer home networking has been widely accepted. Thus, "embedded ethernet module" was designed in this paper for the stabilization of home networking by using 8051 MCU, Hardwired TCP/IP (W3150A). By executing remote software on established simple web-server on the target machine, controlling electric equipment became available elsewhere. With this module, establishing a low-cost home automations system would become possible in a ubiquitous society.

In this paper, In this paper, analyzed structure of home networking used in USN(Ubiquitous Sensor Network) and embedded systems for home automation was implemented on the Android operating system. Developed a system for building a home network using wireless communication, so it is possible to minimize the difficulty of installation. Home automation system has built based on pre-defined ID according electronic components that make a house. In addition, a data structure suitable for home automation was defined and developing application programs based on Android OS according to packet structure, embedded system for home automation was developed.

Middleware enables different networking devices and protocols to inter-operate in ubiquitous home network environments. The UPnP(Universal Plug and Play) middleware, which runs on a PC and is based on the IPv4 protocol, has attracted much interest in the field of home network research since it has versatility. The UPnP, however, cannot be easily accessed via the public Internet since the UPnP devices that provide services and the Control Points that control the devices are configured with non-routable local private or Auto IP networks. The critical question is how to access UPnP network via the public Internet. The purpose of this study is to deal with the non-routability problem in local private and Auto IP networks by improving the conventional Control Point used in UPnP middleware-based home networks. For this purpose, this paper proposes an improved Control Point for accessing and controlling the home network from remote sites via the public Internet, by adding a web server to the conventional Control Point. The improved Control Point is implemented in an embedded GNU/Linux system running on an ARM9 platform.

ZigBee Alliance is a network designed for low-cost and very low-power short-range wireless communications. The ZigBee Alliance is a consortium formed by several leading semiconductor and industrial manufactures, and end users. One of the tasks of this organization is the definition of the networking support and applications profiles that will use IEEE Std 802.15.4-compliant transceivers. In the case of IEEE Std 802.15.4, the ZigBee Alliance is an organization that has led the development of the upper layers, through the definition of application profiles. We have implemented ZigBee home control system, however we have not fully implemented. Because of the ZigBee is not perfectly standarded. We will have to implement according to ZigBee Specifications.

There are some technologies such as USN, RFID, Home-network to advance the ubiquitous era. Those technologies embody Context-Awareness System. To Context-Awareness System is that human, objects and environment supply information with cable and wireless at real time. So private information, information privacy, a wide sense privacy will be faced on serious menace. In this article, I analyze threat of private information in Context-Awareness System under USN(ubiquitous Sensing Network) surroundings and present technology to protect private information. Each technology can apply subdivided protection province information privacy. I expect definition of information privacy, insight through technological presentation and total solution in this article.

홈 네트워킹은 다양한 유ㆍ무선 네트워킹 기술을 적용하여 개개인의 생활을 더 윤택하게 해 주는 서비스를 제공하고 이를 통해 커다란 시장을 형성할 수 있는 미래의 신 성장 동력 산업이다. 이를 위해 PLC, IEEE 1394, HomePNA와 같은 유선 홈 네트워킹 기술은 물론 WLAN, WPAN, UWB 등과 같은 무선 네트워킹 기술이 여러 가지의 응용 분야를 무기로 자신의 영역을 차지하려 하고 있다. 따라서 댁내의 기기는 이와 같은 네트워킹 기술을 지원하도록 설계되어야 하지만, 그 위에 UPnP나 HAVi, Jini, HNCP 등과 같은 미들웨어가 탑재되어야 상호 호환성이 지원된다. 그리고 하나의 표준화된 H/W나 S/W 플랫폼 위에 혼 게이트웨이가 동작하면 집 외부에서 원격으로 새로운 서비스를 지원할 수 있게 되며 응용 분야가 다양하게 확장될 수 있다. 그 위에 유비퀴터스 네트워킹 개념을 도입하여 홈 네트워크가 필요로 하는 서비스를 지원함으로써 커다란 시장을 이끌어 갈 수 있게 된다. 본 논문에서는 홈 네트워킹 기술의 표준화 현황에 대해 정리하고, 차세대 성장 동력으로서의 홈 네트워킹을 위해 반드시 적용해야 할 유비퀴터스 네트워킹 개념과 이로부터 효과를 얻기 위해 집안에 홈 네트워크를 어떻게 수용하게 할 것인지에 대해 논하였다. 끝으로 유비퀴터스 네트리킹을 통한 막대한 시장을 먼저 확보하기 위한 무선 홈 네트워킹 기술의 아키텍처를 정하면서 이를 구현하기 위해 먼저 수행해야 할 Mesh Networking 기술 및 Multi-Hop 네트워킹 기술과 같은 연구분야에 대해 논하였다.(중략)

Cyber-Physical Systems are tight integration of computation, networking and physical objects to sense, monitor, and control the physical world. This paper presents a novel architecture that combines two next generation technologies i.e. cyber-physical systems and Cloud computing to develop a ubiquitous healthcare based infrastructure. Through this infrastructure, patients and elderly people get remote assistance, monitoring of their health conditions and medication while living in proximity of home. Consequently, this leads to major cost savings. However, there are various challenges that need to be overcome before building such systems. These challenges include making system real-time responsive, reliability, stability and privacy. Therefore, in this paper, we propose an architecture that deals with these challenges.
